Fast, Slow, Steep, Smooth, Ride It All In The Right Gear

The SRAM PG-1231 Apex XPLR 12-Speed Cassette brings maximum range, minimum fuss. With over 400%, this puts 2x range in a 1x package and fits on a traditional 11-speed driver body for broad integration.

The smooth cog progression keeps jumps between cogs tightest when it's time to go fast, with more meaningful gaps for climbing.

• For use with XPLR 1x rear derailleurs
• 400% range gives the coverage 1x riders want
• Cog sizes: 11, 12, 13, 15, 17, 19, 21, 24, 28, 32, 38, 44
